Got the set tonight, and as I figured utterly useless. Wind resistance sucks. The beanie and gaiter are a total waste. The sitka windproof beanie and gaiter are so far ahead it's hilarious.
The jacket is really well designed and the fit is awesome. Articulated sleeves as well as the cuff around the wrist that seals it tight. But then pointlessly on the bottom half of the sleeve about the first foot from the cuff there's ZERO insulation and zero wind resistance. You can see the seam in the photos. I can blow air through effortlessly in that spot.
The pants I like better than the jacket. They may be a bit too big for me at 36, but at 34 I know I wouldn't be able to layer much of anything. The pants don't feel constricting and the pocket layout is great.
Unfortunately as I started with, they are not windproof like enkriss said. Non windproof deer hunting cloths are absolutely useless. I'll give them some credit as you do need to give a good huff to push are through them, but you certainly can push air through. The big bad wolf who ate the little pigs couldn't push air through the Stratus set.
As far as insulation they do feel like that inbetween of the Stratus and Fanatic.
I'm sending mine back except maybe the pants as I know either next season or after that Kuiu will take consumer feedback into account and make them windproof. At which time I will certainly be first in line. I'll only keep the pants to try them as I hate bibs and am sick of my stratus ones
I learned my lesson with the FL solitude when that first came out how important for your outer layer to be windproof is.
I thought it was the best whitetail jacket ever made. I got out into 35° woods with a stiff wind and still can't recall a time I was ever that cold and shivering.
